Blood composition and Plasma
Accounting for roughly 92% of blood plasma by volume, this component absorbs heat to serve as an internal temperature buffer
What is water?
Comprising 50% to 70% of circulating white blood cells, these multi-lobed granulocytes act as the frontline phagocytic killers of bacteria
What are neutrophils?
Because their red blood cells express neither A nor B antigens and their plasma contains both anti-A and anti-B antibodies, individuals with this blood type are universal red cell donors
What is Type O?
Constituting roughly 60% of all plasma proteins, this molecule remains in circulation to regulate blood osmolarity and transport fatty acids and steroids
What is albumin?
These bi-lobed granulocytes stain bright red with acidic dye and release specialized cationic proteins to destroy multicellular parasites such as flatworms
What are eosinophils?
Rather than being independent whole cells, circulating platelets are anucleate cytoplasmic fragments shed from these massive bone marrow cells
What are megakaryocytes?
This plasma protein is responsible for transport of immunoglobulins/antibodies.
What is globulins?
Making up under 1% of leukocytes, these cells contain cytoplasmic granules rich in histamine, heparin, serotonin, and prostaglandins
What are basophils?
Recognized by their prominent U-shaped nuclei, these largest agranulocytes leave the bloodstream to become active tissue macrophages
What are monocytes?
In primary hemostasis, this factor binds to exposed collagen fibers within damaged vessel walls, anchoring passing platelets to form a plug
What is von Willebrand factor (vWF)
In healthy blood, formed elements represent around 45% of total volume, with this single cell type making up 99.9% of those elements
What are erythrocytes?
These leukocytes have a single nucleus and are responsible for producing antibodies.
What is B-lymphocytes?
These red blood cell types have the presence of both A and B antigens on their plasma.
What is Blood Type AB.
